I have embed a telerik spreadsheet control in one of my classic asp.net page. The spreadsheet is being loaded with contents of a xlsx spreadsheet. I am using a custom data provider to load the data from the spreadsheet into the Telerik Spreadsheet Control. Below is my code for custom data provider.
public partial class Spreadsheet : Page
private const string ProviderSessionKey = "Demo";
protected void Page_Load(object sender, EventArgs e)
if (Session[ProviderSessionKey] == null || !IsPostBack)
provider = new SpreadsheetDocumentProvider(Server.MapPath("~/App_Data/Visit_Tracker.xlsx"));
Session[ProviderSessionKey] = provider;
provider = (SpreadsheetDocumentProvider) Session[ProviderSessionKey];
rdSpreadsheet1.Provider = provider;
I am able to perform all the operations how ever I want to enable the "History" feature that is available for the workbook class.
I have added the namespace
in my solution however I am not able to access the History object for the spreadsheet control "rdSpreadsheet1"
Can anyone please let me know how to access the history feature for the spreadsheet control.
